Saturninius Secundus Salutius (fl. 355–367) was a Roman official and Neoplatonist author. A native of Gaul, he had a successful career as a provincial governor and officer at the imperial court, becoming a close friend and adviser of the Emperor Julian. Salutius was well versed in Greek philosophy and rhetoric, and had a reputation for competence and incorruptibility in office. He authored a Neoplatonic religious treatise titled On the Gods and the Cosmos, in support of Julian's pagan reaction against Christianity.
